A new method has been developed to generate an extremely high impulsive pressure by using the converging of metal jets. The metal jet is discharged from the collision points, when the metal plate accelerated by the detonation of an explosive collides with a conical concave metal block. The metal jets discharged fly toward the center and collide on the central axis. Then the metal jets exhibit extremely high pressure. Although these rough phenomena have been confirmed by the image obtained by a high-speed camera, the details with regard to the quantity and distribution of the metal jet has been indistinct. Therefore the metal block was put on the central axis and the metal jet that collided with it was observed. The optimal condition that the metal jet is discharged was confirmed.
